Host Cell Proteins, or HCPs, are process-associated protein contaminants that the host bacterium produces during the manufacturing and development of biotherapeutics. It has emerged as a crucial step in the production of biopharmaceuticals, ensuring the safety and efficacy of biological products by identifying and quantifying any residual host cell proteins that can trigger immunogenic reactions in patients.

The market for host cell protein testing is primarily driven by the biopharmaceutical industry's explosive growth and the growing complexity of biological products. The U.S. Food and Drug Administration (FDA) reports that 157 biologics license applications (BLAs) were authorized between 2015 and 2020, indicating a steady increase in the number of approved biological goods. This pattern highlights the growing importance of robust HCP testing procedures in ensuring the efficacy and safety of products.

Moreover, the upgrades to biopharmaceutical research facilities and production facilities have been driven by the growing need for drugs to treat various types of cancer and inflammatory conditions. This need is driving the expansion of biopharmaceutical capabilities, which has further boosted the number of drugs produced. Moreover, the host cell protein testing market is expected to expand due to ongoing research & development efforts related to testing, as well as a growing number of regulatory approvals for testing apparatus.

Additionally, the global market would benefit from the impressive technological advancements in HCP testing equipment, with a focus on enhancing its capabilities and adding more features. Thus, this will accelerate the expansion of the host cell protein testing market.

By Technology, the Enzyme-Linked Immunosorbent Assay (ELISA) Segment is Expected to Drive the Host Cell Protein Testing Market 

The enzyme-linked immunosorbent assay (ELISA) category dominated the host cell protein testing category because these tests are widely used for detecting host cell proteins in biopharmaceutical products, offering strong sensitivity and specificity. These assays are a very dependable instrument in the industry's quality control procedures and have a long history of successful HCP testing. Their status as the market's top sector has been further cemented by their affordability, ease of use, and reliability in extensive testing.

Mammalian Cells Segment by Expression System is Growing at the Highest Rate in the Host Cell Protein Testing Market

In 2024, a significant portion of the host cell protein testing market's revenue came from the mammalian cells segment. This is because therapeutic proteins are increasingly being developed using mammalian cells. Because mammalian cells can create stable formulations with high-yield expression, they are used extensively. They are also favoured because they closely resemble human physiology, making them useful for research and the manufacturing of biopharmaceuticals.
